At which RAID level are FAST Cache drives configured for VNX arrays?
A.
RAID 0
B.
RAID 1
C.
RAID 3
D.
RAID 5
Explanation:
The FAST Cache consists of one or more pairs of mirrored disks (RAID 1) and provides both read
and write caching. For a read caching, the FAST Cache copies data off the disks being accessed
into the FAST Cache.
For protected-write applications, the FAST Cache effectively buffers the data waiting to be written
to disk.
